llvm-mirror/test/Transforms/InstCombine/strcpy_chk.ll
Eric Christopher a671e4f7aa Migrate _chk call lowering from SimplifyLibCalls to InstCombine. Stub
out the remainder of the calls that we should lower in some way and
move the tests to the new correct directory. Fix up tests that are now
optimized more than they were before by -instcombine.
